Definitions
- the present invention relates to automatic milking apparatus and is applicable both to conventional milking machines, as used during the last sixty years or so, and to the "hydraulic" milking machines of GB 2159685 (National Research Development Corporation).
- the basic components of a milking installation are (1) a cluster of four teat cups including (2) a clawpiece, (3) a suction pump and (4) a pulsator.
- Each teat cup contains an annular pulsation chamber defined between a rigid outer casing of the cup and a flexible inner liner which fits over one of the cow's teats.
- the pressure applied by the pulsator to the annular pulsation chamber alternates between a first pulsation value of 50 kPa below atmospheric pressure and a second pulsation value of atmospheric pressure.
- the liner collapses on the teat and the pressure applied by it to the teat causes cessation of milk flow and provides a necessary massage of the teat.
- NL-A-6707881 discloses a milking machine according to the preamble of claim 1, in which this teat massaging effect is improved and thus the milking process is made more efficient. This is achieved in their milking machine by the inclusion of a biassed-open ball valve assembly attached to a teat cup liner upper section. This ball valve assembly functions to maintain the liner at less than atmospheric pressure and opens and closes with each pulsation cycle.
- teat liners are substantially sealed, during milking, from any supply of air to the milk-carrying core regions of the teat liners. Teat liners sealed in this way are hereinafter referred to as pneumatically-isolated teat liners and the method of milking produced, which has certain performance advantages over conventional milking, will hereinafter be referred to as hydraulic milking.
- the mouthpiece of the liner is required to make an initial air-tight seal with the teat in order that the necessary vacuum can be established in the liner core so as to clamp the teat liner on to the teat. Thereafter the teat is extended with pressure of milk from the udder and adhesion between the liner and the teat is principally confined to the barrel portion of the liner.
- the major effect of the teat in the liner is to occlude the passage between the mouthpiece of the liner and the main source of negative pressure beneath the teat.
- an automatic milking apparatus comprising a cluster of teat cups, each of the said teat cups having an annular pulsation chamber defined between a rigid outer casing of the cup and a flexible inner liner which fits over one of the cow's teats, characterised in that the apparatus further includes biassed-closed pressure-responsive non-return valve regulating means having a valve member and a moving part which is arranged somewhere between the uppermost region of the liner and the annular pulsation chamber and operable in response to pressures of less than atmospheric in said uppermost liner region to displace the valve member from its seating and allow air at atmospheric pressure from either the annular pulsation chamber or the outside of the teat cup to enter said uppermost liner region whereby said regulating means is operative automatically to maintain said uppermost liner region at substantially atmospheric pressure throughout the milking process.
- the regulating means is housed wholly within the teat cup.
- the liner includes an intermediate region which (lying between its uppermost region and its body portion) is operative to grip the teat during the main period of milking to provide adhesion there, and to release its grip on the teat during the closing stages of milking in response to a change in teat condition when the udder pressure and milk flow is low thereby to transfer liner grip from said intermediate region of the liner to the mouth region of the liner.
- the regulating means is positioned so as, when open, to allow air at atmospheric pressure to pass direct from outside the teat cup to the uppermost region of the liner.
- valve means there may be four such valve means, one servicing each teat cup (in the liner), or there may be a single such valve means (in the clawpiece, or at the pulsator unit) in which case it will service the whole milking cluster e.g. by a tube to each mouthpiece cavity.
- the invention also provides apparatus in which, during the main milking period, the liner is substantially sealed from any supply of air to the milk-carrying barrel portion of the liner and a short milk tube carries the milk from this portion to a clawpiece having one-way valves within the clawpiece to prevent flow back of milk towards the teat.
- a method of automatic milking using an apparatus in accordance with the present invention in which method the liners are sealed from any supply of air to the milk-carrying barrel regions of the liners during the main milking period thereby to provide hydraulic milking during this period whereas during the closing stages of milking, air is admitted to said regions to provide conventional milking.
- the preferred embodiments of the apparatus of the present invention function only to maintain atmospheric pressure in the upper region of the teat liner with little or no air flow past the teat.
- the barrel of the liner can no longer maintain adhesion with the teat and the adhesion-providing friction point is transferred to the mouthpiece of the liner.
- the teat no longer occludes the passage of air from the mouthpiece to the main negative pressure source and air previously admitted only to the upper region of the liner core now has access to the body portion of the liner core to transport the milk.
- the main disadvantage associated with hydraulic milking is that it requires a somewhat complicated mechanism of air admission to facilitate removal of the cluster from the cow and clear the milk from the system at the end of milking.
- the method and apparatus of the present invention have performance benefits attributable to hydraulic milking without the disadvantages relating to cluster removal.
- the apparatus can be properly cleaned and disinfected during the normal cluster cleaning process of in-place circulation albeit with a suitable extension tube, if necessary, on the valve means.
- FIG. 1 shows, by way of illustration, only two milking units 8 although in practice there will typically be ten or so such units in an average-sized milking installation.
- Each unit 8 consists basically of four teat cups 10, a clawpiece 12, four short milk tubes 14 connecting the teat cups to the clawpiece, and a long milk tube 16 taking the milk from the clawpiece to a recorder jar 18 (or other milk measuring device).
- the bottoms of the recorder jars 18 are connected to a common milk conveyance pipeline 20 although in an alternative embodiment (not shown), the jars 18 (or equivalent) are omitted and the long milk tubes 16 lead directly to the common milk- conveyance pipeline 20.
- Reference numeral 22 indicates the milking vacuum pipeline while reference numeral 24 indicates the air line for the pulsator 26.
- the common milk conveyance pipeline 20 leads to a receiver vessel 28 and in operation of the installation, a milk pump 30 operates to discharge milk from the vessel 28, via pipeline 32, to a bulk tank (not shown).
- the installation further includes the usual sanitary trap 34, vacuum regulator 35, interceptor 36 and vacuum pump 37.
- the teat cup 10 includes a one-way valve assembly 42 sited in a channel 43 in the liner 44. This channel connects the upper mouthpiece region 46 of the liner core with the annular pulsation chamber 48 formed by the cavity between the liner 44 and the teat cup shell 50.
- Reference numeral 51 indicates the pulsation chamber inlet connection.
- valve 42 may best be seen from Figure 3 from which it will be observed that an excess pressure below the valve will move the displaceable valve member (ball 52) upwards into engagement with a bar 54, thereby permitting an upward flow of air through the valve. An excess or equal pressure above the valve, however, will result in ball 52 moving downwards into engagement with a conical valve seating 56 to close the valve.
- the liner 44 When, in operation, at one particular phase of the pulsation cycle, the pressure in the pulsation chamber 48 is atmospheric, the liner 44 will be in a collapsed state so that sufficient pressure is applied to the teat 60 to prevent milk flow. This collapse results from the fact that the pressure (atmospheric) outside the teat wall will currently exceed that within the liner core (50 kPa below atmospheric).
- region 46 is isolated from the liner core below the teat by the grip of the barrel on the teat, there is little tendency for a build up of negative pressure in region 46.
- the valve 42 will ensure that substantially atmospheric pressure will be maintained there even when the seal between the barrel and the teat becomes less effective and is eventually lost towards the end of milking.
- valve 42 there is a higher pressure above the valve 42 (substantially atmospheric) than there is below it (50 kPa below atmospheric), so that the valve will remain closed to inhibit the leak of air at substantially atmospheric pressure from the upper most liner region 46 to the evacuated pulsation chamber 48.
- the mouthpiece ring becomes the point of adhesion. This means that, henceforth, whenever atmospheric air is supplied to the mouthpiece region 46 during the 'atmospheric' phase of the pulsation cycle, it will continue past the teat 60, into the liner 44 and on up the associated short milk tube 14 etc. At this stage, therefore, the apparatus is operating in a conventional milking regime.
- the milk is cleared from the cluster, and take off i.e. removal of the cluster from the cow, despite the one-way milk flow valves, can proceed normally as with a conventional milking system.
- wash tube extension (not shown), allows some beneficial leakage past the valve 42 during circulation cleaning when the clusters are inverted in wash jetters without fear of water violating the pulsation system.
- Figure 4 shows an alternative design of teat cup assembly in which a one-way valve 64 of similar or other type is provided in the distributor block of pulsator 26 between the pulsator distributor chamber 66 and an air bleed chamber 68.
- An air tube 70 connects the bleed chamber 68 with the inlet (71) of the mouthpiece region 46 of the teat liner (as shown), while a similar tube 72 connects the distributor chamber 66 with the inlet 51 for the pulsation chamber 48 of the liner assembly.
- valve 64 operates in a similar fashion to valve 42 in the earlier embodiment and functions, once again, to admit pulsation air at atmospheric pressure (from the bleed chamber 68 to the liner region 46).
- a simulator and valve system can be arranged for air admission at the pulsation relay e.g. using an air transport tube which is continued to the relay on the stall work and connects with the air bleed chamber 68.
- Figure 5 shows another alternative in which a first valve 74 is arranged to be operated by the pulsation chamber pressure to open and close a second valve 76 at the top end of the liner mouthpiece. When open, valve 76 will admit air at atmospheric pressure to the liner region 46 from outside the teat cup.
- teat cup assembly of Figure 5 will function as does the first-described embodiment to provide hydraulic and then conventional milking regimes.
- the teat cup assemblies of Figures 2 to 5 may also be used in an installation for conventional milking which will be essentially as already described with respect to Figure 1, except that some sort of permanent air bleed to the liner core is provided in accordance with the requirements of conventional milking e.g. at the milking cluster clawpiece.
- Figure 6 illustrates this modification, reference number 80 indicating the air bleeds.
- the air bleeds could be provided in the short milk tubes instead of in the clawpieces.
- this is indicated (in broken line) by reference numeral 82 for only one of the short milk tubes in Figure 6.
